The hosts already run a [mini]routing protocol: ICMPv6.

They can learn about multiple routers, and merge router preferences to
select which router should be used for a default router.  They can
detect the loss of a router and switch to using another router on
link.  They can learn about multiple prefixes on link, and cope with
when they go away.  They can even learn about non-default routes, via
RIOs.
